Conceptually the circuit there is simple, consisting of the ultrasonic receiver, followed by a transistor amplifier for the modulated wave, then a diode for demodulation, another transistor ...

But this time the receiving side was swapped out, as [GreatScott] built a basic circuit around a TA7642 AM amplifier/demodulator IC, with only six passive components and a hand-wound coil.

The receiver is equally simple and also based on a CMOS 555. As long as the sensor picks up infrared light from the transmitter, the reset input of the 555 IC is held low and the buzzer is silent.

This infrared repeater system is used to extend the range of an infrared transmitter used at an audio or video equipment at 10 m. The original signal is captured by the infrared receiver (figure 1), ...

Replacing the speaker with an LED results in pulses of light rather than sound. These light pulses are just like Morse code pulses and can be received using the same receiver circuit as the Morse code ...

Targeting OC-192, 10-Gb/s short reach data links, the VSC7166 optical interconnect IC integrates both transmitter and receiver circuits on a single chip. The very-short-reach device converts 16 ...

A transmitter circuit for wireless power transfer systems is Linear Technology’s LTC4125, a high-performance, monolithic full-bridge resonant driver capable of delivering up to 5W wirelessly to ...

The circuit was designed in such a way that this transmitter activated the receiver at the other end of the line but not the receiver next to the sending operator. The active receiver mades a loud ...

Linear Tech has introduced a wireless power transmitter to complement its wireless receiver ICs for the wireless charging market. The LTC4125 is a simple, high performance monolithic full bridge ...
